Looks quite good, though I worry about lack of interoperability between any
service with these goals. I've long wanted something like this in
GeoServer, but was planning to try to make interoperate with at least one
other protocol. Can you directly use a MapFish client with this service?
Like are all the improvements additive?
Are you planning to make it transactional? Or read only? One thing I would
like to see (though certainly not needed in early implementations) is to
also have html representations in addition to the json ones, so it's
browsable by humans. ESRI does a good job with that, including query pages,
like
http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/TaxParcel/ConsumerFocusedPublicAccessMap/MapServer/1/query
Did you consider at all trying to implement the ESRI version? I think they
actually did quite a nice job with the rest api, and they released it as an
'open' standard,
http://www.esri.com/industries/landing-pages/geoservices/geoservices.html I
met some ESRI folks at foss4g and they seem serious about trying to make it
a real open standard, starting an open list to discuss changes and move it
forward with consensus. But as of yet I've not seen that. The really nice
win of implementing it would be that we'd get real interoperability, with
esri flex, javascript, silverlight and iphone clients. And we could cascade
arcgis server.
The other two that jump to mind are http://featureserver.org/ and
http://www.jasonbirch.com/nodes/2009/01/31/269/mapguide-rest-extension-feedback-wanted/
And yes, there's wfs basic as Ian points out, but I'm not sure that there's
any implementations of it? Maybe cubewerx?
No matter what I think it'd be a great community module. We could
theoretically have several rest services in community modules. But to get
in to extension I'd like to see one that actually interoperates with several
clients and at least one other server. Perhaps once we flesh them out we
could suggest the changes to the mapfish protocol. Or ultimately see if we
could agree with ESRI and perhaps put the final results in to OGC
eventually.
